1 Claim. (Cl. 189-315) This invention relates to an improvement in pole band fittings such as those used to attach guy wires to wood poles which support electrical power distribution lines.

Wood provides a natural dielectric which has never been equaled by any other practical material that might be used to make poles. However, wood poles are used as nature made them, of varying shapes, sizes, and irregularities. Hence, it is often diflicult to find a smooth section on the pole surface where a rigid pole band can be fit. The impossibility of standardizing the cross-sectional dimensions is another factor that makes a rigid pole band unuseable on many poles.

This invention is a development of my pending patent application Cable-Flex Pole Band, Serial No. 242,544, filed August 18, 1951, now Patent Number 2,703,216, and assigned to the same assignee as this application. My cable-flex pole band provided a strong and flexible pole band that was adaptable to various sized and shaped poles and which distributed the stress evenly around the pole. I used cables swaged to guying fixtures to achieve this.

The object of this invention is to provide a flexible pole band composed of metal links held together by drill rod or any other suitable material.

Another object of this invention is to provide a flexible pole band to which links can be facilely added or removed in order to conform to irregularities in pole surfaces.

Other objects will appear from time to time in the course of the specification and claim.

An embodiment of my inventive idea is illustrated in the accompanying drawings in which:

Fig. 1 is a section through a pole taken just above the pole band.

Fig. 2 is a side elevation of my flexible link pole band.

Fig. 3 is a perspective view of one type of pole band take-olf lug.

Fig. 4 is a perspective View of a fastening means for my flexible link pole band.

Like reference characters indicate like parts through out.

Figs. 1 and 2 illustrate the flexible link type of pole band 1 adapted to a standard wooden pole. Note that the band constitutes conterminous groups of superposed elongated links 2 which are stamped from strip steel. Each group of links 2 is pivotally connected to an adjacent group by means of a rod 3 which may be made from drill rod or any other material having high resistance to shearing stresses. Rods 3 are retained against removal from links 2 by split pins 4 or any other suitable means. By connecting any predetermined number of groups composed of links 2 by rods 3 an articulated band is formed which wraps around a pole in the manner illustrated in the drawing.

For fastening a guying cable to the pole band 1 a perforated take-off lug 5, illustrated in detail in Fig. 3, may be interposed between adjacent link groups and pivotally secured thereto by rods 3 in the same manner in which the groups of links 2 are interconnected. From examining the drawings it should be clear that additional take-off lugs 5 may be inserted in the pole band 1 to suit an installation where it is desired to connect a plurality of guy wires to the band through the medium of the take-off lugs.

In Fig. l diametrically opposite from take-off lug 5, band 1 is provided with a pair of end lugs or fastening means 6 for connecting the ends of the band together. Details of the fastening means 6 are most clearly apparent in Fig. 4. That figure shows the fastening means 6 to have a U-shaped cross sectional configuration defining a central channel-like passage 9 for receiving a connecting bolt 10 when the band 1 is clamped to a wooden pole. Extended wall portions 7 integral with fastening means 6 are then pinned to links 2 by a rod 3 and retained by split pins 4.

The preferred width for the pole band would be three links wide as this number would provide the best distribution of stress. The two intermediate links would then be of slightly thicker material than the two outside links and the center links. However, when the length of band 1 is increased as described heretofore, it is preferable to increase the width of the band by super-posing additional links 2 in each group and lengthening pins 3 accordingly.

The pole band design disclosed herein may be rearranged for fastening to various sized poles by the simple expedient of adding or removing links from the articulate assembly. In addition, the band is inherently capable of accommodating a pole having appreciable peripheral irregularity because of its being made of short links which tend to pivot on each other into conformity with the contour of the pole. Moreover, the band may be readily tightened, by means of a single bolt, until the links dig into the wood, thereby positively preventing slipping or sagging of the band.

I claim:

An articulated pole band for attaching guy wires to a pole comprising, a plurality of conterminous links superposed in spaced relation to each other to form endwise overlapping link groups, pivot rods projecting through the overlapping ends of adjacent link groups normal to their respective planes and hingedly connecting said link groups together, means for retaining said pivot rods in said links, a take-off lug interposed between adjacent link groups and hingedly connected thereto by means of said pivot rods, said take-off lug comprising a pair of similar links each having portions oppositely olfset into contact with each other intermediate said pivot rods and extending radially from said pole band, a pair of opposed U-shaped end lugs each having perforate side walls extending into overlapping relation with an adjacent link group and connected thereto by means of said pivot rods, bolt means engaging each end lug, whereby said end lugs may be urged toward each other for tightening said band on said pole.
